Note: The Excel projects are not dependent on the operating system (XP SP3 / Vista / Windows 7. - Vista/Win7 32-bit or 64-bit)
Also, not dependent on MS Office version (2003 SP3 / 2007 SP2 or SP3 / 2010 SP1 / 2013/2016/OFFICE 365). Office 2010 32-bit only. MS Office 64-bit is known to give VBA problems and is not supported and should be installed on a PC only if the user needs Excel projects needing over 2GB of memory. If needed, please download Service Packs From These Links
If you are using the project on a hard disk that is connected to a network (more than one PC), then you need the network version.
If you are using the project from a pen drive (External - removable drive), you need to purchase for the removable version.
If you are using the project from a fixed drive (your notebook or desktop hard disks that are not networked / shared to other PCs) you should make a payment for the fixed version.
When the project opens it automatically recognizes the type of hard disk / removable disk it is installed to and whether it is a network drive or not. Then it looks for the corresponding license file. If found, the project runs OK. If not, there will be some ‘Trial’ limitations.
4. Known Issues -
With Office 2013 - There is a slight but perceptible screen flicker when the computing is being executed. By contrast, screen rendering is extraordinarily smooth with earlier versions of Excel. The screen flicker with Office 2013 is a known issue with Microsoft and they may or may not attempt to provide a fix as the cause seems to be "changes that are made in Microsoft Office 2013 to optimize the new graphics engine."
With Office 2010 - Our products need clean and updated installations of Windows XP SP3 or later and Microsoft Office 2003 or later. Microsoft India has confirmed to us by online chat support that Office 2003 or 2007 (especially 2007) must be completely uninstalled before the user installs Office 2010. If you have installed Office 2010 'On top of' Office 2007 or 2003 you are likely to face problems with this product and many other Excel workbooks with user-defined functions or macros. Please refer to http://support.microsoft.com/kb/971179 & http://support.microsoft.com/kb/928218. When installed properly, Office 2010 is a pleasure to use.
You may need to go through all the steps including the steps for manually removing previous versions before installing Office 2010.
